IMPROVEMENT IN CORN-SHELLERS.

Specification forming part of Letters Patent No. 166,77 1, dated August 17, 1875; application filed April 30, 1875.

To all whom it may concern:

Be it known that we, \VILLIAIiI H. HALL and CONRAD S. YINGST, of'lifiin, in thecounty of Seneca and State of Ohio, have invented a new and useful Improvement in Corn Shellcrs, of which we declare the following to be a full, clear, and exact description, reference being had to the accompanying drawing forming part of this specification, which is a perspective view of the hopper and the manner of attaching the said improx'ement.

In order to enable others skilled in the art to which our invention appertains to make and use the same, we will now proceed to describe its construction and operation.

The object and purpose of our invention is to construct an improved attachment to cornshellcrs, for the purpose of pressing the corn against the shelling-wheel, that shall be fully as etfcetive as anyin use, and made at less cost.

This we propose to accomplish by the savingot' all the labor of fitting the several parts together, each part being used just as it comes from the mold, without any dressing whatever, except one hole drilled in the back R.

We now proceed to describe its construc tion The cheek-pieces A A are made with small recesses, B, into which the pin 0, which is cast in the head or top of the rubbing-iron D, rest. The rubbing-iron D is constructed with the usual serrated edge and circle at the lower end, but to which we lay no claim, and it is inserted in the cavity formed by the cheekpieces A A and the back E, which, together,

form a good and suilicient guide to hold the same in proper position. Through the back E a hole, F, is drilled, for the passage of the entended end of the spring II, which is marked L, which reaches over the top of the rubbing iron I), for the purpose of holding it in the proper position-that is, to prevent its rising. The bolt 1 passes through the back E and the spring 1]., the pressure being regulatodby the fly-nut J.

Having thus described the construction and operation of our improved hopper for cornshellers, we say that no claim is made to the form of hopper, neither to the manner of at tachment to the frame, or the lower end of the rub-iron, or to the spring H, except the projecting end.

What we do claim, and wish to secure by Letters Patent, is-

The cheelrpieces A A,formed with a recess in the top edge for the reception of the pin which suspends the rulriron, said rub-iron being secured by the end of thespring LI, marked L, the end L of the spring H passing through the hole F in the back E, against which the rub-iron D rests, in combination with the hopper K, constructed as described, and for the purpose set forth.

In witness that we claim the above we hereunto set our hands this 24th day of April, A. D. 1875.
